The linear momentum of the electron in the ground state of H-atom is 2 xx 10^(-24) kg m//s, its linear momentum in the 8^(th) orbit is

Answer»

`2.5 xx 10^(-25) kg m//s`
`5.2 xx 10^(-25) kg m//s`
`5.2 xx 10^(-15) kg m//s`
`2.5 xx 10^(-15) kg m//s`

SOLUTION :`P_(n)=P_(1)/n`
`:. P_(8)=P_(1)/8=(2xx10^(-24))/8=2.5xx10^(-25)` kg m/s
